and normal summer clothes, what remains in your BOB, and what does it weigh? Mine is 14 lbs, then 4-8 lbs of water (depending upon the area and threats) 1-3 lbs of food, 5 lbs of armor, 11 lbs of guns, gun gear and ammo, about 1 lb of NVD stuff. So the BOB weight can vary, mostly depending upon armor and full gun gear (or just pocket pistol) between 21 and 42 lbs. and that extra 20 lbs, you FEEL it, after hiking hills, brush, mud, for 10 miles, 5-6 hours. It does start to slow down your responses and make you more prone to injury and oversights. tack on another 20-30 lbs, and it flat starts to get really stupid. All the gear and skill in the world won't mean a thing if you wrench a knee or ankle. Y0u'll be sitting there deciding when to shoot yourself, that's all. Before or after all the agony of the next few hours/days. So you have to be really in shape, practicing with such weight, all the time, on your type of terrain, or you'd better keep the BOB pretty danged lightweight.
